Yep... Self supporting... Thats why it tends to be a struggle with such a large casting box, I'm realy pushng it for what my backyard operation can do, but this one supprised me so I'm happy for now... and its given me some new ideas for the next one.That is freaking amazing! So just for clarity, the cavity in the sand is hollow and is self supporting? Or did I miss something?
